• Do not store, install, or operate the product in any of the following locations.
• Locations subject to direct sunlight.
• Locations subject to temperatures outside the range specified in the specifications.
• Locations subject to humidity outside the range specified in the specifications.
• Locations subject to condensation resulting from severe changes in temperature.
• Locations subject to corrosive or flammable gases.
• Locations subject to exposure to combustibles.

Transporting, Installation, and Wiring
■
• Always use the original shipping box when transporting the Inverter.
• Do not apply excessive shock to the Inverter or drop the Inverter. The Inverter may malfunction
or may be damaged.
• Do not connect an AC power supply voltage to the U, V, and W output terminals. Doing so will
damage the Inverter.
• Do not connect any load other than a three-phase inductive motor to the U, V, and W output
terminals.
• Do not connect an AC power supply voltage to the control I/O terminals. Doing so will damage
the Inverter.
• Use 600-V polyvinyl chloride (PVC) cable with a wire size of 0.75 to 2 mm
circuit terminals. Also, tighten the terminal screws on the terminal block to a torque of 0.8 to
1.0 N·m.
• Take appropriate and sufficient shielding countermeasures when installing systems in the fol-
lowing locations. Not doing so may result in malfunction or equipment damage.
• Locations subject to static electricity or other forms of noise.
• Locations subject to strong electromagnetic fields and magnetic fields.
• Locations close to power lines.
Operation and Maintenance
■
• This Inverter can be set to operate from low speed to high speed. Operate the Inverter only
after sufficiently confirming the allowable range for the motor installation being used.
• Take measures to assure safety before performing maintenance or inspection, or replacing
components.
